Review on Stainless FastenerU Fasteners Replacement Motorcycle by Minas Chase

The description says it's made of 304 stainless steel AND is nickel plated on the bottom, not quite sure why it says so. I received my order and found that they have mixed materials, only M4 is 304 stainless steel, M6 and above are nickel plated steel, they will rust. It is clear that if you buy such multipacks, they tried to deceive buyers, they are always made of the same material. Didn't specify, the description was very vague. If you look at the seller's photo then the nuts in the top left corner are a different shade of silver than the rest which are more of a blue colour. On top of that, it's not Amazon Prime and comes from China, too much hassle with returns.
